Abstract Previous experiments have attempted to measure smooth pursuit eye movements (SPEM) to acoustic targets with limited success. Some studies found no evidence for SPEM (Gauthier and Hofferer, 1967; Schaefer et al., 1981; Boucher et al., 2004; Berryhill et al., 2006) and other studies found only a sub-set of subjects could produce SPEM, which was poor in quality (Krukowski et al., 2001; Hashiba et al., 1996; Cloninger et al., 2013, 2014). These findings are despite evidence of auditory motion perception and an auditory motion aftereffect in the psychoacoustic literature (Carlile and Best, 2002; Dong et al., 2000). This thesis explored a multi-modal question, whether sounds can facilitate or interfere with pursuit of a visual target by moving congruent with or incongruent with linear visual motion, and did so using high-fidelity eye tracking that allowed for examination of the main pursuit characteristics: latency, open-loop acceleration, open-loop peak acceleration, steady-state gain (i.e., eye velocity/ target velocity), and number of “catch-up” saccades. Results showed evidence of facilitation in some characteristics (open-loop peak acceleration) but no evidence of interference, possibly due to the strength of the visual stimulus.
